Abstract: High quality EMD was prepared from a bath containing suspended MnO2. The method is capable of using current density up to 1.3A/dm2 on titanium electrode with postponded passivation on Ti surface. EMD thus obtained had a specific surface of 79m2/g instead of 34m2/g for that obtained by commom method.

Key words: electrolytic manganese dioxide, preparation
